My experience with bonnie and thrux owners is thattheydon'treallyridedd or fast, maybe just the guys around here, but most of them are into the small twin triumphs for the image and comroderie of a different flavor than the HD type.
Those type of riders will be very well suited by the lower end torque.
On the otherhand, neutering the small twin may be a way of making the 1200 twin seem like a value to a buyer why test rides both, and thus justify the drastic pice difference between the ST and the ThruxR.
What is funny though, is that every single Dayton 675, Speed Triple, or R3 owner I have come across has generally been a rediculous Hoon, myself included.
